SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

此技能提供一种简单、鲁棒的方式，通过 Redis 的键存在性来控制工作流暂停，从而避免正在运行的任务造成资源浪费与状态不一致。通过设置一个 TTL 为 60 秒的停止标志键，确保键不会因为异常而长期存在；工作流完成后会主动清除该键以释放资源。

Core Features & Use Cases

  • 设置停止标志: 使用 setAgentRuntimeStop 为指定 appId 与 chatId 设置停止信号，TTL 60 秒。
  • 检查是否应该暂停: 使用 shouldWorkflowStop 根据 Redis 键是否存在判断工作流是否应当暂停。
  • 清除停止信号: 使用 delAgentRuntimeStopSign 当工作流完成后清除信号，确保后续可继续运行。
  • 等待完成: 使用 waitForWorkflowComplete 轮询检查停止标志是否被删除，在超时前等待信号解除。
  • 鲁棒性设计: Redis 操作失败时降级为继续执行，避免阻塞工作流。

Quick Start

  1. 将暂停信号应用于指定 appId 与 chatId：调用 setAgentRuntimeStop({ appId: 'your_app_id', chatId: 'your_chat_id' })。
  2. 让工作流进入暂停状态：重复调用 waitForWorkflowComplete({ appId: 'your_app_id', chatId: 'your_chat_id' })，直到停止标志被删除。
  3. 工作流完成后清除停止信号：调用 delAgentRuntimeStopSign({ appId: 'your_app_id', chatId: 'your_chat_id' })。

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I pause a running workflow using Redis?▼

Pause workflows by setting a Redis-backed stop flag with setAgentRuntimeStop, specifying your appId and chatId. The flag persists for 60 seconds with automatic TTL cleanup, enabling immediate stop signaling across distributed workflow instances.

Can I stop a workflow without blocking execution if Redis fails?▼

Yes. This Skill degrades gracefully—if Redis operations fail, the workflow continues executing rather than blocking. This robust design prevents Redis errors from halting your automation pipeline.

How do I check whether a workflow should pause?▼

Use shouldWorkflowStop to poll Redis and determine if a stop flag exists for your workflow instance. The function checks key existence, making pause decisions immediate and deterministic.

What happens after a workflow completes—do I need to clean up the stop signal?▼

Yes. Call delAgentRuntimeStopSign after completion to remove the stop flag and release resources. This prevents orphaned signals and ensures subsequent workflow runs start in a clean state.

How do I wait for a workflow to finish pausing?▼

Use waitForWorkflowComplete with your appId and chatId to poll until the stop flag is deleted. This polling-based mechanism waits up to a timeout before returning, supporting synchronous workflow completion checks.

Does this pause mechanism work for per-app, per-chat workflow isolation?▼

Yes. The Skill applies stop signals to individual appId and chatId pairs, enabling isolated pause control across multiple concurrent workflows without cross-contamination.
